Hey, i had trouble finding that last "T" fuse and i saw here that i am not the only one. I actually had to start over and here is the way to go.

You have to find 6 "T" fuses before you lift the shark. The "L" fuses are worthless. You can check how many you found by pressing the D-pad up and checking the suitcase in the lower right corner of your inventory.

Once you got the 6 "T" fuses you can lift the shark. You will see one single "+" fuse go into your inventory but when you check you'll see that you actually got 3 of those "+" fuses.
